Best of the Newsgroups: printing to D-Link DP-300U

The dlink web site and some user reviews on shopping site both imply that it supports LPD and neither mentions raw tcp on any port nor uses the term jetdirect anywhere. Based on the <a href="ftp://ftp.dlink.com/Printserver/dp300U/QIG/DP300U_QIG_100.zip">documentation</a> I'd just use LPD. And from that same document, apparently you should point a browser at the devices ip and go to the lpr setup page to find out (or define your own) the port names to use as lpd/lpr queue names. IE: for parallel port 1, it might be echo this is a test |rlpr -P PS-1123D6...@192.168.0.20 You can use the native lpr support in sco, except you lose the use of printer interface scripts then, unless you set up dummy loopback or lp-wrapper printers as described in a few articles on pcunix.com Personally I only ever use this: http://www.aljex.com/bkw/sco/#rlpnc and this with it. http://www.aljex.com/bkw/sco/#rlpr The first provides a convenient way to use netcat and rlpr, and includes netcat already, in an out of the way place thet the included printer model script expects, but which won't clobber or interfer with any other netcat binary you may already have. The second adds rlpr as a seperate package that the first is already prepared to use. Basically just unpack the two tars, create printer(s) in scoadmin using device /dev/null and model Net, and edit a line in /etc/printers where the first field is the same as the name of the Net printer. In your case it would look like: If the printer is named "accounting", the DP300U's IP is 192.160.0.20, and the printer is on parallel 1 accounting:192.168.0.20:PS-1123D6-P1:rlpr:HPLaserJet:comments... comments should be info about printer model, print server model, physical port, mac address, etc... You'll probably need to mark the model scripts executable before the Net model will work, since it works by just running one of the other model scripts in-place instead of by having you copy and edit it. chmod 755 /usr/spool/lp/model/* You may also want to mark the rlpr binary suid so that is has permission to access priviledged tcp ports. chmod +s /usr/local/bin/rlpr The advantage here is that, unlike using the native lpr support, the resulting printer is just like an ordinary local printer. You get the use of printer interface scripts just like usual, any printer interface script, not just one you hand-edit to insert netcat functionality, and you get it without having to set up two printers in the OS for every real printer. (an lpr printer which can't use an interface script, and a wrapper lp-to-lp printer that provides the interface script) You never copy or edit any scripts. You just define a printer in scoadmin and edit or create a line in a config file. Also, thereafter, when that printer changes ip or connection type or even interface script (model) , you just edit the config line and the change takes effect with the very next print job, no restarting anything or even going into scoadmin. -- Brian K.
